System Inspection

  1. Visual Inspection
    1. Check the air hose between MAFS and throttle body is torn or installation.
    2. Check deformation, crack or installation of throttle valve (body)
    3. Has a problem been found ?

      YES 

      • Substitute with a known-good Air hose or throttle body and check for proper operation. If the problem is corrected, replace air hose or throttle body and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

      • Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM.

    Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others

    PROCEDURE OF ETS INITIALIZATION 

    1. Erase the trouble codes on PCM
    2. Turn the ignition key off and keep this condition until the main relay is turned off. (It will takes 10sec.)
    3. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
